The ferrule fitting is formed in one with connector rod to be made.
The ferrule fitting is arranged on the head end of connector rod.
The ferrule fitting is arranged between joint rod head end and tail end, and the distance with joint rod head end is L.
Positioning boss in the protective jacket head end opening is male half coupling, the internal diameter of male half coupling be more than the diameter of connector rod and
Less than the diameter of ferrule fitting.
Positioning boss in the protective jacket head end opening is the positioning tooth of multiple centripetal extension same distances, these positioning
Tooth divides equally 360 ° of circumference, and diameter of a circle where the elongated end of each positioning tooth is more than the diameter of connector rod and is less than the straight of ferrule fitting
Footpath.
Had the advantages that using above-mentioned technical proposal：
1st, a ferrule fitting is fixedly installed in connector rod, the diameter of the ferrule fitting is more than the diameter of connector rod, cutting ferrule
The axial end of joint towards connector rod tail end is the conical surface, and the periphery of the ferrule fitting is provided with annular slot, the protection
The positioning boss that centripetal extension is provided with the opening of head end is covered, the protective jacket is socketed in connector rod, towards ferrule fitting movement,
Positioning boss in protective jacket head end opening is strutted after deformation by the conical surface of ferrule fitting, is moved to the position of annular slot, is returned
Bullet is caught in the annular slot of ferrule fitting, forms axially position, due to being fixedly connected between ferrule fitting and connector rod, when
After the positioning boss of protective jacket is caught in the annular slot of ferrule fitting, by two cell walls of annular slot to the convex of protective jacket
Platform axial limiting, had both facilitated and protective jacket is assembled in connector rod, constituted connector rod combination, meanwhile, protective jacket is in connector rod
Good positioning effect, will not be axially moveable, and keep the long-time at butt joint rod rear end pilot hole to cover.
2nd, the ferrule fitting is arranged between joint rod head end and tail end, and the distance with joint rod head end is L, can basis
Actual use is it needs to be determined that the position of ferrule fitting, axle positions the position of protective jacket.
3rd, the positioning boss in the protective jacket head end opening is the positioning tooth of multiple centripetal extension same distances, and these are determined
Position tooth divides equally 360 ° of circumference, and diameter of a circle where the elongated end of each positioning tooth is more than the diameter of connector rod and is less than ferrule fitting
Diameter, due to having spacing distance between each positioning tooth, each positioning tooth is when the ferrule fitting conical surface goes out extrusion, deformation model
Enclose larger, beneficial to assembling, each positioning tooth is caught in after the annular slot of ferrule fitting, equally there is good axle positioning to protective jacket
Effect.
It is further described with reference to the accompanying drawings and detailed description.
